\versionadded{1.5.2}
|
|
|
|
The \class{netrc} class parses and encapsulates the netrc file format
|
|
used by the \UNIX{} \program{ftp} program and other FTP clients.
|
|
|
|
\begin{classdesc}{netrc}{\optional{file}}
|
|
A \class{netrc} instance or subclass instance encapsulates data from
|
|
a netrc file. The initialization argument, if present, specifies the
|
|
file to parse. If no argument is given, the file \file{.netrc} in the
|
|
user's home directory will be read. Parse errors will raise
|
|
\exception{NetrcParseError} with diagnostic information including the
|
|
file name, line number, and terminating token.
|
|
\end{classdesc}
|
|
|
|
\begin{excdesc}{NetrcParseError}
|
|
Exception raised by the \class{netrc} class when syntactical errors
|
|
are encountered in source text. Instances of this exception provide
|
|
three interesting attributes: \member{msg} is a textual explanation
|
|
of the error, \member{filename} is the name of the source file, and
|
|
\member{lineno} gives the line number on which the error was found.
|
|
\end{excdesc}

|
\subsection{netrc Objects \label{netrc-objects}}
|
|
|
|
A \class{netrc} instance has the following methods:
|
|
|
|
\begin{methoddesc}{authenticators}{host}
|
|
Return a 3-tuple \code{(\var{login}, \var{account}, \var{password})}
|
|
of authenticators for \var{host}. If the netrc file did not
|
|
contain an entry for the given host, return the tuple associated with
|
|
the `default' entry. If neither matching host nor default entry is
|
|
available, return \code{None}.
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}{__repr__}{}
|
|
Dump the class data as a string in the format of a netrc file.
|
|
(This discards comments and may reorder the entries.)
|
|
\end{methoddesc}
|
|
|
|
Instances of \class{netrc} have public instance variables:
|
|
|
|
\begin{memberdesc}{hosts}
|
|
Dictionary mapping host names to \code{(\var{login}, \var{account},
|
|
\var{password})} tuples. The `default' entry, if any, is represented
|
|
as a pseudo-host by that name.
|
|
\end{memberdesc}
|
|
|
|
\begin{memberdesc}{macros}
|
|
Dictionary mapping macro names to string lists.
|
|
\end{memberdesc}
